Please help, I'm too indifferent to math to actually have an opinion.
Olin [163]

Math to me is very complicated. I know that I need it in life, but when have you ever needed to find the square root of the distance from the sun to mars on a normal day-to-day basis? But jokes aside, I know that I do math without thinking about it. It is important, even for the jobs that you would think that you would NEVER need it (even English teachers do it, haha.) Overall, math is kinda iffy. In my opinion, you can't live with it, but you <u>really</u> can't live without it.
